👉 Polymixiiformes is a family of mammals known for their large, complex brains, which are more developed than those of other mammals and have a higher level of complexity in visual perception compared to other vertebrates. They are characterized by features such as long limbs with strong muscles and a wide range of sensory organs. Polymixiiformes are primarily found in the tropics and subtropics, where they inhabit dense forests, grasslands, and even rocky terrain.
